Application Vertical Motion Model
Objective â—? Predict how long it will take for an object to fall from a given height â—? Determine the height from which an object has been dropped using the vertical motion model
Materials Partner, paper, pencil, timer (phone), calculator, objects
Choose 2 objects that you can drop
Decide on a location that you can drop your objects
Let’s Get Started Record the following information on your worksheet: 1.
Describe your starting location. ________________________________
2.
What 2 objects are you going to drop for the activity?_____________________
3.
Predict how long it will take object 1 to hit the ground.___________________
4.
Predict how long it will take object 2 to hit the ground.___________________
5.
Predict the height at which you are dropping your objects.________________
Let the trials begin... 1. 2. 3. 4. 5. 6. 7. 8.
Set up your starting point for object 1. Have your partner ready with the timer. The timer starts when the object is dropped. Stop the timer when it hits the floor. Record the time on your data sheet. Repeat so you have 5 trials with the same object. Repeat the process with your second object. Calculate the start height to the nearest tenth.
Data Collection Worksheet
Drawing Conclusions Analyze your data and answer the questions on the worksheet. Questions to consider: ● ● ● ●
Were your predictions close? Was your data collection consistent? Explain. Are your results reasonable? How would you know? If you could alter the experiment, what would you do differently to assure more accurate data collection?
